You could try using the -t flag (time in seconds) to record for a
fixed duration of one hour, then start another ecasound process with
your script.

I've used ecasound to encode to Vorbis on the fly, like this, I
recall:
ecasound -i:/dev/dsp -o:somefile.ogg -z:intbuf -z:db -r -t:3600
>From the manpage:
'-z:db,dbsize' enables double-buffering for audio objects that support
it (dbsize=0 for default, otherwise buffer size in sample frames).
'-z:intbuf' and '-z:nointbuf' control whether extra internal buffering
is allowed for realtime devices.
-r:sched_priority
Use realtime scheduling policy.
Cheers
Daniel
